That depends highly upon the materials used and the construction. I have yet to do any testing myself but materials like abs and petg are known to be waterproof if not water tight. Once I do some testing though I will make some more informed decisions.
Thanks, that maf issue is good to know about I’ll keep my eyes up for it.
I promise PETG and ABS are not waterproof lol, They will both leak like hell. You might be able to get it to not take on water with a resin printer but conventional FDM printers will not print anything that resembles a water resistant. I work for a 3D printer manufacturer, we test everything from PLA to TPU and not just through our printers. We have found nothing that holds or keeps out water.
I’m assuming all of these tests were straight off the printer bed. My intention would be to figure out through some testing and research of my own which material along with a method of post processing like vapor honing, epoxy/resin would give me the best results. My theory is, If people are makin flower vases and toy boats using FDM printers then there is probably a way of making prints watertight
LOL. The final results might be different but as of right now my test pieces of basic pla have yet to take on a single drop of water. Now 4 hours in to being submerged. I’ve got multiple pieces with different print settings and a control with default settings that I’ll leave submerged for the next 24 hours but so far results are promising even for the cheap pla. Dry as a bone even with .8mm walls
Well more power to ya, i wouldn’t trust it on my truck without some Phil swift goodness.
